In carrying out my invention, I make use of upright supporting members 1 and 2 spaced apart as shown in Figures 1 and 4. Channel members 3 are securedto the members land 2 by means of bolts 4, seeFigures 1 and 4. Supporting brace members 5 are also secured to the upright members 1- and2 by means of bolts 6. -The members so far defined are preferably cut from channel iron but may be of any'other suitable material. Suitable cross brace members 7 may be secured to the upper ends of the upright members 1 and 2 as shown in Figures 1 and 4. The cross members 7 support longitudinal frame members 8. The members 8 may be bolted to the cross members 7 by means of bolts 9. A

In Figure '1 I have shown the ends of the longitudinal frame members 8 as being connected with one end of a sticking unit 10. The members 8 are properly aligned with the sticking unit so that the stock which is ejected from the sticking unit will be passed onto a table 11 carried by the members 8.

The table terminates at 12, see Figure 1. A' companion table 13 is mounted upon the op posite ends of the members 8 and terminates m st-motions such as that used in connection Figures 1,. 3,.and 5:

at 14. Pairs of brackets 15 and 16 are mounted upon suitable channel members 17 and 18, v respectively. The brackets are spaced apart as shown in Figure 4. A guidev block 19 is disposed between the upper ends of each pair of brackets, see Figures 4 and 2. The blocks are provided with a V-shaped groove 20. Each block is provided with an elongated opening 21, see Figure 2, for receiving a bolt 22. A suitable bolt 23, see Figure 4, is provided in conjunctionwith=eaclrof the bolts 22 whereby the upper ends of each pair of brackets may be firmly secured together and rigidly supported by means of, one. of. the members 8. The lowerends ofeach pair of brackets are provided with flange portions 24, see Figure 1,.whereby the bases of the brackets may berigidly secured to the channels 17 and 18 by means of bolts 25. A: wheel; 26 having a V-shaped groovei27 is disposed: between each pair of brackets 15" and 16.

A movable-carriage-28 is dis-posed between the-bracketsnl5 and the brackets 16;. The

carriage is provided with taperedi edges'29- and 30 which are guided: by the V-shaped grooves 20 and 27, respectively. The carriage 28 is providedwith an: upper bearing: portion 31 and a lower bearing portion 32-, see Side spindles 33 and a center spindle 34 are mounted: within the beaning; portions 31 and: 32. The: spindles are arranged for reciprocatorymovement With-respect totheinlongitudinal axes.- The lowerends-of the spindles are provided with" hearing members 34 having splined relation; withtherspin'dles. Eachcspindle isprovided with such a splined construction, see Figure 1. Each of'the spindles 33 isrprovided: with a gear 35. These: gears are disposediin-mesh with a gear 36 associated. with the central spindle. A. bevel gear 37 is connected; with the gear 36 and is disposed: in mesh'with a. sliding bevel gear; 38; Thegears and 36 1 may be rotatedthrougli the medium of the bevelgears S'Tand 38; Rotation of the latter will cause the bearing; members 34' which have splined' relation With-the spindles 33' and 341 to turn the spindles. Splined concutter 40 comprises: a: head portion 41:,[see

Figures 8 and 9, having cuttingblades 42 secured thereto by means-of screws or bolts 43. The blades are provided with spirally arranged cutting; edges 44.; In Figure 7 I have shown a pair of sash 'rails- 45, and 46 having tenon portions 47.. The bits 39' cut' recesses 48in the ends of the sash: rails. The cutter 4O cooperates withthebits 39' for rel:-

ishing the sash rails as indicated at 49. The 7 and the bits 39 are slightly'below the upper surfaceoi th'e tablell Figure 3 shows the positions of the cutter and the bits with respect to the table, while the former are in their elevated position for cutting the relish. A pair of guide members 50 is mounted upon the portions 31 and-32, see Figures: 1 and'2. The" guide membersarezarranged to movably su) orta s acer'com r-isin '.v ortions 51 P10.-

K b i b idly connected together by r means of cross members-52 and;53. It will-be noted that the upper ends-0t theportionsb'l project slightly abovethe. upper face-oftthe table 11. The

purpose. of this constructionwi-ll be defined later. in'connectionwith-the explanation of the operationiotthe.mechanism.. A lever 54 is pivotally connected at 55 with one of the portions50.-. The. lever is provided with a cam; portion 56. The opposite end of the lever is operatively eonnectedwith the cross member 53,.see1Figunes 1,.2, and.5. A brack et 57. is securedto the portion:-32, see Figure5,

and isa-r ranged to support one end of a spring 58 .whiclrbears. agninstthe under edge of the:

cross member 53. The cross member 53. is

provided with a guide rod 59 which passes through: anopening in the bracket The spring 58tendsto hold the spacing device or portionsfilintheir.normal position shown in Figures 1 and: 2. When. the carriage 28. is

moved from the full line position to the dotted line position. shown in Figure 2, the

cam: portion .5.6 engages aroller 6O carriedby.

one of: the brackets 16.. At this time the spaceris moved. downwardly for. positioning theends. of. theportions 51- below the upper surface ot the table 11. It will also be noted iii .refei'ring.to.Figure 2:that. the cutter 40 and thebits 3.9 arexin their elevatedposition when the carriage is in its shifted position.

A.movable.frame 61 comprising end portions 62. and. 63 and. crossmembers 64 and 65 prisingupright bracket members 67, and a cross member 68. The bracket, portions 67 are mounted upon the-table 11. and secured thereto by means of bolts, 69, see Figure 4. The frame 61 is .movably connected with respect to'thesupportingframe 66 through the medium of a screw 70, see Figure 1. Rotation of the screw 7 0 will cause an upward or downward movement of the frame 61, depending upon the direction ofrotation of the screw 7 O.

Referring now to Figures 2' and 6, it will be notedithat the. cross member 65 associated 'ismountedupon a supporting frame 66com- I with the frame 61 is provided with a recess 71 within which a slide 7 2 and a companion slide 73are disposed. The recessis provided with tapered walls for retaining the slide members 7 2 and 73, as shown in Figure 6. The

slide 72 is providedwith a bracket 74. Thebracket is secured to the slide by means of bolts or screws 75. A lever 76 having slot 77 is mounted upon the connecting portion 7 8 between the horizontal portions 64 and 65. The slot 77 permits longitudinal movement of the lever 76. A retaining bolt 79 holds the lever upon the portion 78. The lever is connected with the bracket 74 through the medium of a link 80. The lower end of the lever is operatively connected with a companion slide 73 at 81. Movement of the slide 72 will cause a movement of the companion slide 73 through the medium of the bracket 74., the link 80, and the lever 76'. The slide 72 and the companion slide 7 3 are shown in their normal positions in Figure 2. A guide mem-' ber 82 is secured to the frame 61, see Figures 2 and 4, by means of bolts 83, see also Figure 6. Companion guide members 84 are secured to the tables 11 and 13 and are disposed in alignment with the guide 82.

The rails which are to be relished are ejected from the sticking unit which I have indicated generally at upon the table 11 and are held snugly. against the guides '82 and 8% by reason of spring members 85 associated with posts 86 carried by brackets 87. The sash rails are ejected from the sticking unit onto the table 11 in a continuous line. The tenons are bored and relished while passing over the tables 11 and 13in a continuous line. The tenon on one end of a sash rail abuts against the tenon of another rail. In Figure 2 I have shown the tenons of two sash rails at 88 and 89. In Figure 7 I have indicated thesash rails as being. provided with shoulders 90. A shoulder is .provided upon each side of the tenon. WVhen the stock is ejected from the sticking unit, each piece is passed onto the table 11 and moved in the direction of the relishing unit.

Referring now to Figure 2, it will be seen that the shoulder 90 associated with a piece of stock indicated at 91 will engage a push dog 92 mounted upon a plate 93 which is fixed to the slide 72. The push dog is mounted for movement about a bolt or other suitable supporting member 94. The rail is held against the guides 82 and 8 1 by reason of the spring members 85, see Figures 4 and 6.

When the shoulder 90' associated with the rail 91 has engaged the push dog 92, the sliding bar 72 and the companion bar 73 will be caused to move in the direction of an arrow 95, see Figure 2. The movement of the slide 7 2 will cause the lever 76 to be moved from in engagement with the push dog 92 will engage a cam surface 97 for moving the dog machine and the slide72 and the companion slide 7 3 are moved back to their normal position by means of a spring 98.

Let us assume that one sash rail has already passed the push dog 92 and that there is a continuous line of sash rails passing through the unit. The end of one of the tenons associated with the rail 91 will engage the end of a tenon on the end of a rail in advance of the rail .91 at X. Whenthe tenons of the two rails reach the point indicated at' the full line position to the dotted line position andthe dog 99 will be also moved from the full line position to the dotted line position. At this time the shoulder 90 associated with the rail in advance of the rail 91 Willbe positioned in a plane indicated at W in F igure 2. The upper ends of the members 51.

are depressed and held in a plane on a level with the upper surface of the table 11. In other words, the ends of the spacer bear against the underneath edge of the sash rail passing over the particular point at which the members 51 are positioned. Now going back to the full line position of the parts shown in Figure 2 continued movement of the sash rails through the relishing machine; I

will bring the shoulder 90 associated with the rail 91 in engagement with a stop portion 100 associated. withone of the members 51,

see Figures 5 and 8, and the stop portion 100 associated with the other oi the members 51 will engagethe shoulder of the advance rail as indicated at W in Figure 2. 7

As the rail 91 is pushed through the machine,.the carriage 28 will be moved from the full line position shown in Figure'2 to the dotted line position. The spacer holds the rails apart at a predetermined distance. Duringthe movement of the carriage from its full line position to its dotted line posi tion, the cuttertO and the bits 39 will have movedfromthe full line position to the dotted line position. Such movement of the cutterand the bits provides the grooved'and relished stock as shown in Figure 7. The means for, elevating the cutter and the bits will be defined later.

When the carriage is in the dotted line position, the cam portion 56 is riding upon the wheel 60. Movement of the lever 54 upon which the cam portion 56 is provided causes the spacer to be depressed for movingthe upper ends of the members 51 below. the,

underneath. side: of: the rail 91. A. slight monementof the rail will. bring it into. position.v for holding thev spacer in its depressed position until a pair of rails has again been spaced apartfor permitting the spacer to en- -:the other rail in spaced; relation with the firstmentioned rail during the relishing process, willspush thelatter; Let us now refer to Figures2 and 3. Figure2 shows-one side of-the tail view of the slide.

.A, yoke 101. is associated with the spindles 33 and 34:. Thespindles are provided: with. collars 102. an-df103', see also Figure 5. Theyoke 101 is provided with a wheel 104 which is arranged: to ride upon a slide 105. The slide is mounted forimovement about an aXis comprising a bolt or other suitable supporting means indicated at 106 The slide maybe moved about the axis 106, as will be defined later.. The wheel 104 engages the slide when the wheel is in the dotted line position 107.

Since the wheel is fixed: with respect to the yoke 101,.it will be seen that the spindlesg'd and 3% will be lifted a distance equal to the vertical distance between the-position 107. and theposition 10S shown in Figure 3.

ing action. The carriage in Figure .3' is shown in a shiftediposition. In fact, the carriage has substantially completed itsshifted The slide 105 is associated with movement. r a bracket 109 which moves with the slide when the latter is dropped. In referring to. Figure 3, it will be noted: that the wheel has engageda cam 110, and that the cam is provided with a cam surface lll arranged to move the wheel downwardly as the carnage moves'in'thedirection of an arrow 1 12. The bracket 109 is provided with a-spring113 whichnormally holds the slide in the inclined position shown in Figures 3 and 1-0. The spring 113 is provided for moving the bracket from its dotted line position to the full line position shown in Figure 3 when the carriage moves back 'to its normal position.

The wheel'104eis arranged to run upon the upper edge of the bracket 109,asshown in As the carriage continues in 'its movement in the direction of the arrow 112, the cam 110 will tend to move the slide downvw'ardly a-boutits pivot 106. The slide is locked in its inclined position during the time that the wheel is moving from the position shown at'107 to the position shown at 108. a projecting portion 134- which is slotted at The wheel 10a is j ection 118 which is-normally positioned for.

engaging a pin 119 carried by the bracket,

. whereby theslide issuploorted in its inclined The lever is pivotally mounted: at

position. I 120-upon astationary framemember 121. A slight movement o-f'the carriage after the arm 11'1 has engaged the collar 115will move the lever'from its full line position to its dotted line position, at which time the projection 118 will be moved from underneath the pin 119.

Continued movement of the carriage at this time will cause the wheel 104 to be moved downwardly by reason of the cam surface 111. Such movement of thewheel will of course lower the cutter and the bits which have been lifted upwardly by reason of the yoke associated with the wheel'. The weight of the yoke, the cutter and the bits, and their associated mechanism will ordinarily move the slide and the bracket to the dotted line position shown in Figure 3. The cam provides means whereby the return of the cutter and the bits is made certain. The cam' may be adjusted by means'of a screw bar 122. This dis tance is equal to the amount that the tenons After the slide: has been returned to its normal position, the upper edge of the slide is: aligned in a plane occupied by the bracket 109 shown in Figure 3. As soon as the wheel reaches the position shown in Figureg; that is, when the wheel is positioned above the.

from its dotted line position to the full line position, at which time the projection 118 will be positioned underneath the pin 119 for supporting the slide in itselevated position. In Figure2 I have shown the sliding bevel gear 38 as being operatively connected with a bracket 124. The gear 38 has splined' relation with respect to a drive shaft'125'which is supported at its ends by means of'bearings 126'and 127. The shaft may be operatively connected with a power shaft 128 which may be operatively connected with any suitable source of power, not shown.

Referring now to Figure 10, it will be noted that I have provided a bolt 129 which has a swivel connection at 130 with a member 131 associated-with the slide 105'. The bracket 109 is provided with a pin 132 having a threaded opening for receiving the threaded portion of the bolt 129. The bolt is provided with a head 133 which permits the bolt to be turnedmanually for adjusting theinclination of the slide with respect'to the bracket; The'bracket is provided with V of may be readily understood.

185 for permitting the member 131 to be; slidably mounted. Thus it will be seen that a slight rotation ofthe head 133 will change the inclination of the slide, depending of course upon the direction in which the bolt is turned.

From the foregoing description of the various parts of the device, the operation there- The sash rails are ejected from the sticking unit onto, the table 11 and moved through the relishing machine in a continuous line. The sash rails are relished during the movement of the rails through the machine. In Figure 2 I have shown the normal position of the carriage 28 and the sliding bars-72 and 73.

Let us assume that a continuous line of sash F- rails is passing through the machine. A shoulder of one rail will engage the push dog 92 which tends to assume an upright position by reason of a spring 136. When the push dog is in its full" line position, the dog is rigidly supported by means of the release dog 96 which is held in engagement with the push dog by reason of a spring 137. When the carriage is in its normal position, the dog 99 will befin engagement with the shoulder associated with the rail in advance of the rail 91. At this time, the spacer is in its depressed position. "As therail 91 continues its movement through; the machine, the sliding bars 72 and 73 will be moved, at which time the sliding bar 73 will be moved faster than the bar 72 wherebv the do 92 will be moved from its full line position to the dotted line position, and the dog 99 from its full line position to the dotted line position.

When the dogs are thus positioned, the spacer will be moved upwardly sufficiently far, whereby one of the shoulders associated with the rail 91 will engage one of the members 51. and thereby cause a movement of the carriage 28. Almost simultaneously the other member 51 associated with the-Spacer will engage the shoulder associated with the rail in advance of the rail 91, whereby the two rails are held in spaced relation and at the same time move in unison with the carriage 28. The movement of the carriage at this time is from the full line position shown in Figure 2 to its dotted line position. During the movement of the carriage, the'wheel 104: associated with the yoke 101 will ride upon the slide 105 for elevating the cutter and bits from their lower position shown in Figure 2 to the elevated position shown in Figure 3. Such movement of the cutter and bits will complete the relishing and grooving of the tenons associated with the spacer. hen the carriage is in its shifted position, the lever 54 will engage the wheel for depressing the spacer and the cutter and bits I will be moved downwardly for permitting 'riage.
